Westerbeke 10-2 RPM too fast when warm
I have a 1987 O'Day 272 with West 10/2. Last season, I noticed that upon engine start up RPM was was good, if I remember right about 800 RPM idle, maybe 700.. Within a minute or two though, the RPM would increase to about 1200 and stay there at idle.
Any thoughts on what would cause this? I would think if I decreased the idle speed, it would be too slow when cold......
